Hi,
I am new to Dummynet. I would like to setup a FreeBSD QoS box to replace
the one using Linux IMQ. However, I have the following questions :-
1. Is it possible to cascade pipes, such that the bandwidth management
could be easier by hierarchical control rather than flat-out? For instance,
pipe 100 is the total bandwidth 2Mbps of the serial link to Internet
pipe 110 cascade pipe 100 with a weight 8Kbps and ceiling 16 Kbps
pipe 120 cascade pipe 100 with a weight 32Kbps and ceiling 256 Kbps
pipe 130 cascade pipe 100 with a weight 384Kbps and ceiling 2Mbps
pipe 140 cascade pipe 100 with a weight 224Kbps and ceiling 2Mbps
Pipe 130 and pipe 140 are allowed to consume the total bandwidth if
there is no other traffic, but would only get its share 224 / (8 + 32 +
384 + 224) when all pipes are fully loaded.
2. Is there any FIFO queue rather WFQ? If there are 3 queues defined top
sahre the bandwidth of pipe 110, how to make the traffic to go in FIFO
manner?
Thanks a lot.
John Mok
